This page explains, at a high level, how we arrive at a valuation view for each company we cover, and what the figures on each stock page mean. We keep the underlying analytical process confidential, but the inputs we rely on and the outputs you see are described here in full.
Each company on this site is assessed by combining a quantitative valuation model with in-depth fundamental research grounded in primary sources, principally regulatory filings and company reports. The valuation model estimates a company's intrinsic worth from its financial fundamentals: cash generation, growth, and profitability. Independent research then tests, refines, and where warranted overrides that estimate, drawing on recent filings, earnings calls, and management commentary that a quantitative model alone cannot fully capture.
For every company, this process produces three things: an estimated fair value, a verdict describing how today's price compares with that estimate, and a confidence level describing how strong and well corroborated the underlying evidence is. In cases where a company's reported figures are ambiguous or inconsistent across sources, we rely more heavily on the qualitative research view and hold confidence at Low until the picture is clearer.
Our fair value estimate is our best judgment of what a company is genuinely worth today, based on its financial fundamentals, not simply where its stock happens to be trading. We typically express it as a range rather than a single number: a conservative estimate, a base case estimate, and an optimistic estimate, each reflecting a different set of assumptions about how the business could perform from here. A stock trading above that range looks expensive by our analysis; one trading below it looks inexpensive. These are estimates, not guarantees, and they will change as new information becomes available.
Undervalued means today's price sits meaningfully below our estimated fair value range. Fairly valued means today's price sits within, or close to, that range. Overvalued means today's price sits meaningfully above it.
Confidence reflects how strong, consistent, and well corroborated the evidence behind a verdict is, not how large a price move we expect. We express it as one of four levels.
Highest means our research reached a clear, well supported view of fair value, and that view is corroborated by our other checks.
High means our research reached a clear view, and there are no material concerns about the reliability of the underlying figures.
Medium means the overall picture is consistent but comes with a caveat worth noting, for example an adjustment made for a distortion in reported figures.
Low covers a few situations: our research has not yet reached a clear view, in-depth research on this company is still underway, or the underlying data was not reliable enough to weigh in with confidence. If in-depth research on a company has not yet been completed, we note that clearly on its page, and confidence remains Low until it has.
Financial figures come primarily from SEC filings (10-Ks, 10-Qs, and 8-Ks) via SEC EDGAR, along with company earnings releases and shareholder letters, supplemented by market price data. Our research also draws on reputable secondary sources, principally major financial press, where relevant. Each stock page includes a collapsed “Sources” section listing the specific filings and articles used, with dates.
This site provides educational information only. It is not investment advice, a recommendation to buy or sell any security, or a substitute for independent judgment and research. Our valuations are estimates built from historical and reported data. They can be inaccurate, they will change over time, and they should not be relied upon as the sole basis for any investment decision.
